SEBA Checker-2 Versatile water quality measurement in surface water • • • • • Mobile, compact field laboratory for measuring water quality parameters (e.g. oxygen, pH, conductivity, redox potential, turbidity) in surface waters Spiral cable with stainless steel coupling for SEBA multi-parameter probes of the MPS-D3/D8/K16 3-line backlit LCD Integrated logger for manual and / or automatic storage of measured values (optional)

Mobile water quality measurement Quality Measurements with SEBA Checker-2 The SEBA Multi-parameter system Checker-2 has been developed as a mobile field laboratory especially for determination of water quality parameters in surface water. The Checker-2 has an extremely compact design, easy operation with fast and precise acquisition of various water quality parameters. The current measured values are clearly displayed. Optionally, the instrument can be equipped with an integrated data logger with a storage capacity of up to 1,120,000 values for an automatic or manual data recording. Data Logger...
